Walter-titex 5059422 Jobber Drill Bit 1/8 Inch Hss

Product Description

The WALTER-TITEX 5059422 is a jobber-length twist drill bit designed for high-performance metal drilling in trade and industrial applications. Built from high speed steel (HSS) with an oxide coating, this 1/8-inch diameter bit features a parabolic flute geometry and a web-thinned, tapered web construction that reduces thrust force and improves chip evacuation. The 130-degree split point starts on contact without a center punch. With an overall length of 2-9/16 inches and a straight-cylindrical shank, it fits standard drill chucks and quick-change systems. This bit is rated for high-performance use in production and service environments.

The 5059422 is well-suited for drilling blind holes and stack drilling operations in cast iron, non-ferrous metals, and steel. The parabolic flute profile supports efficient chip clearing in deep-hole work, with a maximum drilling depth of 1.181 inches (30 mm). Electricians, plumbers, HVAC technicians, and general trade professionals use jobber-length bits like this for structural steel, sheet metal, and mechanical component work where precise, clean-entry holes are required.
